AOAC Method SMPR 2016.015 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Identification of Animal-Derived Proteins in Dietary Supplements

AOAC SMPR 2016.015 defines the required performance characteristics for identifying animal-derived proteins in dietary supplements. These proteins include whey, casein, egg, and other milk-based sources, which must be detected even when adulterated with nonprotein ingredients such as melamine, taurine, or free amino acids. Methods must accurately identify these proteins at concentrations as low as 0.1% with a minimum 90% probability of identification (POI) and demonstrate no false positives at zero concentration. At higher concentrations such as 10%, the method must return 100% correct identifications. These performance expectations apply across various product types and matrix complexities.

The recommended instrumentation must support high specificity and sensitivity, particularly in the presence of common supplement additives or adulterants. LC-MS/MS systems are preferred due to their precision in detecting source-specific peptides and proteins. Instruments must also support reproducible identification across laboratories and matrix types, meeting both single-lab and multilab validation requirements. The systems listed below are compatible with SMPR 2016.015 and, when validated properly, provide reliable results for regulated protein source verification.
